Static vs Dynamic Routing

• Static Routing:

  • Forwarding table entries are manually configured by an administrator.
  • Advantages:
    • Provides more control.
    • Can be used for non-destination-based forwarding.
  • Disadvantages:
    • Doesn’t scale well.
    • Slow to adapt to network changes.

• Dynamic Routing:

  • Routers use routing protocols to exchange network information and compute the best routes.
  • Advantages:
    • Adapts quickly to changes in network topology.
    • Scalable for large networks.
  • Disadvantages:
    • Complex distributed algorithms.
    • Higher resource consumption (CPU, bandwidth, memory).
    • Difficult to debug.
